Fig. 1-5 illustrates printer 50, and this printer has the ribbon cartridge according to first embodiment of the invention.Printer 50 has can be along support or the carriage and the base 52 of the traverse motion of printer, and it is the part of this carriage.Printer 50 has ribbon cartridge 10 and printhead 54 (Fig. 3).
In Fig. 1 and 2, the base 52 of printer 50 has: swinging mounting part 56 is used for swingingly supporting ribbon cartridge 10; Supporting part 58 is used for being different from the position supporting ribbon cartridge 10 of swinging mounting part 56; And ribbon driving device 60.Cross out a pin 24 from the side surface of box body 12, swinging mounting part 56 has a hole, to hold pin 24.Thereby ribbon cartridge 10 can be swung with respect to base 52 around the axis of pin 24.With respect to swinging mounting part 56, with the position of supporting part 58 opposition sides, 62 pairs of ribbon cartridge 10 biasings of spring are arranged.
An a pair of wheel 20 walking belt wheel 20 and 22 that is arranged in box body 12 is driving wheels, and another is taken turns 22 and is driven pulley, is driven by driving wheel 20. Walk belt wheel 20 and 22 and be the wheel of gear shape, there is tooth its neighboring.The tooth of walking belt wheel 20 and 22 is meshing with each other, thereby colour band 14 is from passing through to transmit colour band 14 between them.The ribbon driving device 60 of printer 50 is a driving shaft, and when ribbon cartridge 10 was packed printer 50 into, this was installed in away in the hole of belt wheel 20.Ribbon driving device 60 is by the motor-driven that is located in the printer 50.
The driving mechanism that is used to swing box body 12 is housed in the box body 12.This driving mechanism is arranged to and can be received rotatory force from the ribbon driving device 60 of printer 50, with swing box body 12.Specifically, this driving mechanism comprises: pinion 26 is contained in away on the axle 21 of belt wheel 20; Cam 30 has and pinion 26 meshed gears 28; Connecting rod 34 is connected with cam 30.
Therefore, the rotation of ribbon driving device 60 is through walking belt wheel 20 and pinion 26 passes to cam 30, so cam 30 rotates.Because the lower end of connecting rod 34 rests on the supporting part 58 of base 52, connecting rod 34 can not move both vertically.In cam 30 rotation processes, when the higher part of cam face 32 contacts with connecting rod 34, box body 12 (box end arm 18) is around upwards swing of pin 24, when the contacting with connecting rod 34 of cam face 32 than lower part, box body 12 (box end arm 18) around pin 24 to lower swing.Ribbon cartridge 10 reciprocally swingings are shown in arrow B among Fig. 1.
The swaying direction of ribbon cartridge 10 is consistent with the width of colour band 14.The pin 24 of determining oscillation center is positioned at belt wheel 20 next doors, and box end arm 18 is positioned at end, the distance of box body 12 and walks belt wheel 20 farthest.Therefore, although the higher part of cam face 32 and very little than the difference between the lower part, and box end arm 18 can move both vertically fully along the width of colour band 14.
Fig. 4 has shown the colour band of printing (colour band that is used to print) 14.Print track is illustrated by letter " A ".Print track moves on near colour band 14 lower ends gradually from close colour band 14 upper ends, and from moving on to gradually again near colour band 14 upper ends near colour band 14 lower ends.In other words, by horizontal mobile box body 12 along colour band 14, can the print area of colour band 14 is extending transversely.
Therefore, not that the given zone at colour band 14 repeats printing, so when reusing colour band 14, colour band 14 can local damage, the durability of colour band 14 improves.For example, after producing 6,000,000 print points, do not have finish the service life of the conventional ribbon cartridge of drive unit, and have ribbon cartridge according to drive unit of the present invention, extend to its service life produce 12,000,000 print points after.In this embodiment, the gear ratio between the gear 28 of pinion 26 and cam 30 is 1: 6, and cam face 32 is shown in Fig. 8 A.Especially when printing straight line, be that the same area at paper prints operation basically, but in the case, the position of colour band 14 also change, colour band 14 can local damage.
In addition, owing to be used for swinging box body 12, therefore need not to increase special motor or solenoid is swung box body so that the print area of colour band 14 driving mechanism extending transversely is to work by receiving the rotatory force of rotating colour bands 14 from printer 50.And owing to can use existing element (as walking belt wheel 20) structure driving mechanism, the driving mechanism structure that therefore is used to swing box body 12 is simple.In addition,, therefore need not to change printer itself because driving mechanism can be contained in box body 12 inside, and the printer of ribbon cartridge 10 of the present invention may being packed into, to substitute the conventional ribbon cartridge of no driving mechanism.
In Fig. 4, the width of colour band 14 is by letter " C " expression, and the print zone width of colour band 14 is by letter " D " expression.In addition, the ink supply sector width is by letter " E " expression.Herein, the width E in ink supply district is less than the print zone width D.For example, the width C of colour band 14 is 13 millimeters, and the print zone width D is 7.5 millimeters, and ink supply sector width E is 5.5 millimeters.
In Fig. 3, box body 12 contains oil tank, and the felts ink supply element 36 that is full of printing ink wherein is housed.Ink supply element 36 has low-density felt part and high density felt part, the high density felt partly with contact for the belt wheel 22 of walking of driven pulley.Therefore, by ink supply element 36 with walk belt wheel 22 to colour band 14 ink supply.
Ink supply sector width E and ink supply element 36 are with to walk belt wheel 22 contacted end width corresponding.Colour band is to be made by the material that is easy to ink permeation.If ink supply sector width E equates that with the print zone width D printing ink can permeate and assemble in above and below the section of print zone, printing ink is from the up-and-down boundary zone of these sections infiltration print zones then, makes the last lower limb blackening of institute's printable character.When half print zone is used to print, especially this tendency can appear.Therefore, by ink supply sector width E is designed to less than the print zone width D, printing ink is seeped into the up-and-down boundary zone of print zone from the section above and below print zone, and printing ink evenly distributes in printing section, therefore can obtain clean printing effect.
In addition, arrange of the inboard ink supply of ink supply element 36 to colour band 14 circles.Under situation shown in Figure 3, ink supply element 36 contacts with the driven belt wheel 22 of walking, and this takes turns the inboard that is located at colour band 14 circles.At box end arm 18, printhead 54 is located at the inboard of colour band 14 circles, and printing paper is located at the outside of colour band 14 circles.By this structure arrangement, can prevent that colour band from staiing printing paper in the vertical and horizontal motion.
In addition, as shown in Figure 5, cam 30 has centre bore 31, and the driven belt wheel 22 of walking has axle 23, and the centre bore 31 of cam 30 freely is assemblied on this axle.By this structure arrangement, need not to cam 30 provides special axle, and overall structure becomes simple.In addition, because cam 30 and walk the rotating speed difference between the belt wheel 22 and rotation direction is identical, the interference between them is less, and is no problem in the practicality.
Fig. 6 illustrates the another kind of topology example that is used to support cam 30.Box body 12 has fixing ring-shaped sleeve 40, is positioned on the upper wall 38 of box body.Sleeve 40 is located between the centre bore 31 of the driven axle 23 of walking belt wheel 22 and cam 30, thereby the bearing effect is played to driven spools 23 of the belt wheel 22 of walking in the inboard that makes sleeve 40, and the outside of sleeve 40 is used to support cam 30 as axle.Arrangement in this way when gear ratio between the gear 28 of pinion 26 and cam 30 strengthens, can be eliminated cam 30 and the driven interference of walking between the belt wheel 22, and keeps the driven structure of walking belt wheel constant in the mode of routine.This is suitable for using with structure shown in Figure 10.
Figure 10 has shown an example, and wherein the gear ratio between the gear 28 of pinion 26 and cam 30 can change.Pinion 26 along the circumferential direction has one toothed portion and a no toothed portion is arranged.Therefore, when pinion 26 rotates a week, tooth is all arranged and rotate the situation in a week and compare in whole periphery with pinion 26, therefore the amount of spin of the former cam 30 can improve the gear ratio between pinion 26 and the cam 30 less than the latter.If it is big that gear ratio becomes, also become the hunting period of ribbon cartridge 10 greatly, the characteristic that moves both vertically of printing shown in Figure 4 also changes.
The characteristic of printing that moves both vertically also can be changed by the shape of the cam face 32 of cam 30.
In Fig. 7 A and 7B, cam 30 is designed so that cam face 32 has higher part 32a and than lower part 32b, higher and have vertical coupling part than between lower part 32a and the 32b.This structure can be avoided concentrating printing at the middle body of colour band 14.
In Fig. 8 A to 8B, cam 30 is designed so that cam face 32 has higher part 32a and than lower part 32b, higher and than lower part 32a and 32b between have the coupling part 32c of inclination.The stretching, extension angle of the coupling part 32c that tilts respectively is 40 degree.This structure can be avoided concentrating printing at the middle body of colour band 14, and has alleviated the increase by cam face 32 height caused torque loads of flip-flop or impact.
In Fig. 9 A to 9B, cam 30 is designed so that cam face 32 has higher part 32a and than lower part 32b, higher and than lower part 32a and 32b between have the coupling part 32c and the 32d of inclination, and it is, longer from higher part 32a Zhong Yan to inclination coupling part 32d than lower part 32b from the inclination coupling part 32c ratio of the higher part 32a that stretches than lower part 32b from the rotation direction of cam face 32.This structure can further be alleviated the increase of torque load.
